My daughter is preparing for the ACT test, and she asked me about a question on her practice test. I don't know how to go about this problem...hoping someone here can explain it.
"The Smiths plan to roof their cabin on 2 consecutive days. During the week they plan to roof the cabin, there is a 20% chance of rain each day. Assuming that the chance of rain is independent of the day, what is the probability that it will rain both days?"
The answer key shows 4% as the correct answer. If someone can tell us how to solve the problem, we would be appreciative.
